Answer:
![6x-7](https://tex.z-dn.net/?f=6x-7)
Step-by-step explanation:
![\frac{1}{3} (12x + 6x -21)](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%20%2812x%20%2B%206x%20-21%29)
break it into pieces
![\frac{1}{3}*12x = 4x](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%2A12x%20%3D%204x)
![\frac{1}{3}*6x=2x](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%2A6x%3D2x)
![\frac{1}{3} *-21=-7](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%20%2A-21%3D-7)
put it all together
*since there's no negative in front of the other numbers except 7 they're positive so you add them*
![4x + 2x - 7](https://tex.z-dn.net/?f=4x%20%2B%202x%20-%207)
simplify
![6x - 7](https://tex.z-dn.net/?f=6x%20-%207)

Step-by-step explanation:
a = 14
b = 4
h= 5
Area of trapezium =
( a + b) h =
(14+4) 5
=
x 18 x 5 = 6 x 5 <em> [I solved </em>
<em> and 18]</em>
= 30!
